Roller Seal Replacement Kit
Greensmaster DPA Cutting Units
Part No. 107–1594
Form No. 3350–953
Installation Instructions
1. Remove the roller from the cutting unit.
2. Remove the nut, seal and old bearing from each end of
the roller.
Note: Make sure the seating surface of each nut is not
damaged. If nut is damaged, replace with Toro Part No.
106–6939.
Note: To ease the removal of the roller nuts, thread a bolt
and jam nut into each end of roller shaft.
3. Install a new bearing, a black assembly washer and old
nut onto each end of the roller (Fig. 1).
Note: If new nuts are to be used, use the old nuts, if
possible, for installing the bearings and seals. This will
preserve the patch lock feature in the nut. Use the new
nuts only after the new bearings and seals are installed.
4. Tighten the nuts until the bearings are seated on each
end of the roller (Fig. 1).
